To all w hom t may (2o/acera Be it known that l, DAVID Soi-mae, acitizen of the United States, and resident ot' New York City, in thecounty of New York and State oi New York, have invented certain new anduseful lmprovements in Combination Tools, of which the following is aspecilication.

My invention relates to combination tools and has for its object toprovide a simple and el'licient tool ot this class in which a pluralityof elements of special utility in connection with the ignition system ofan. internal combustion engine are conveniently combined. Other morespecific objects ot my invention will appear from the descriptionhereinafter and the `features ot novelty will be pointed out in theappended claim.

ln the accompanying drawings which illustrate an example of my inventionWithout detining its limits, l41 igure 1 is an elevation oi. thecombination tool, and llig. 2 a cross-section thereoi" on the line 2-2o'i Fig. l.

.its shown, the combination tool comprises a main section or shank 5,the free end ot which is fashioned in the -form ot a Wrench. 6dimensioned with special regard to the customary hexagonal or similarelements whereby, for instance, the breaker points of distributingblocks included in ignition systems ot the well-known type are generallysecured in place. The shank 5 is 'lfurther provided with continuingmembers 7 spaced apart in parallel relation and having their tree endsturned inwardly to constititue an end member 8 and thereby term a closedrecess in which an abrasive device, preferably in the form oi acomposition stone 9, is secured in any convenient manner. ln theprefered arrangement the stone 9 is grooved to fit the inner surfaces otthe members 7 and is held against removal by the inturned ends 8thereof, as shown. rlhe transverse thickness ol:l the stone 9corresponds to the Width oi the members 7 and 8, said stone being oi asize and shape other- Wise to iit the recess formed by said meinbers Zand 8. rlhe tool further comprises gage plates 10 and ll constructed oisheet metal having a thickness corresponding, tor instance, to thedistance between the spark or breaker points of a distributing block or.in other Words, to the spark gap thereoi, the plate l0 being, forinstance, of an inch in thickness While the plate ll is, for

instance, of an inchthiek, these two dimensions representing` thedistances apart at which the breaker points oit such dis-` tributing`block provi-de the most ei'iicient spark. rlhe plates 10 and ll are o'la sii/5e to completely cover the opposite iaces ot thev stone and aremovably incorporated in the tool, for instance by being` pivoted at l2,so as to be capable of covering and uncovering said stone as desired.

'lhe plates l0 and 1l in addition, therefore, to serving as gages tocorrectly gage the spacing or the breaker points, serve 'further asprotectors whereby the eilfective faces ot the stone 9 are protectedwhen not in use. rlhis is of importance to prevent in-` jury to orbreaking of' said stone when the 'combination tool is carried in a toolbox with numerous other tools and implements. The stone 9, it will beunderstood, is useiful for rubbing oil all rough and projecting spotsfrom the spark points and 'for adequately and eitlicieutly cleaning` thesame. Furthermore, the plates l0 and ll, when in their normal positions,constitute continnations ot the shank 5 and torni a handle therefor orcomplete the handle structure whereby the wrench may be manipulated.rlhe wrench b is ot a size to readily tit the nuts olf' existingignition devices and may be eiliciently utilized to adjust the same forsecuring breaker points and the like in position and to disconnect thesame.

The combination tool provides a serviceable implement which may bereadily carried about and in which a plurality oi? instrumentalities arecombined in a single structure; in other Words, the tool in itsillustrated form provides a Wrench, a stone, and gages adaptedparticularly :tor adjusting the breaker points ot Delco, Bosch, andlsman ignition systems, and in tact all `electric systems in whichplat'iuun'i and tungsten points are used.

rlhe tool makes it 'unnecessary to remove the breaker points or theirequivalent i'roin the ignition system when it is desired to clean thesaine and at the same time guarantees a proper adjust-ment thereof in asimple and ecient manner.

`While the tool is intended primarily for use as herein indicated, it isobvious that it may be otherwise utilized to advantage it desired.

Various changes in the specific torni 10 pivotally mounted upon saidshank and normally lying in registry with said stone to cover theopposite surfaces thereof, said plates being pivotally movable topositions transverse to said shank to uncover the snrfaces of saidstone.

Signed at the city of New York in the county of New York and State ofNew York this lst dav of April, 1921.
